Hi Jim, Which direction was your data flow? Here are my numbers, for a 5272 based board (one of our SnapGear LITE routers), connected to an no-name PC (AMD 1.4GHz CPU running RedHat 7.2). The is tcpblasting from the PC to the 5272 board: TCP 6283 msec = 13037053.6 b/s = 1629631.7 B/s = 1591.44 KB/s UDP 877 msec = 93400009.1 b/s = 11675001.1 B/s = 11401.37 KB/s Regards Greg Henderson, Jim wrote: > Using the following configuration: > > 5272 board uClinux kernel 2.4, running tcpblast to send 9999 packets of > 1KB each using both TCP and UDP > Server Gateway 266 MHz running RedHat Linux 7.2 > > Our 5272 board was connected directly to the server (no hub/switch) and the > following measurements were taken: > > TCP 9410 ms = 8704000 bps = 1088000 Bps > UDP 5480 ms = 14944000 bps = 1868000 Bps > > Note that the UDP performance suffered because the server was unable to > accommodate the extreme UDP traffic and refused 10 of the connection > attempts. > > Does this throughput seem reasonable or should I expect higher performance? > > > > > ------------------------------------------------------------------------ > This email may contain confidential information and/or copyright material. > This email is intended for the use of the addressee only.
